Filing an FDA Prior Notice yourself means submitting detailed shipment information through the FDA's PNSI portal before your goods ship to the USA.
The FDA provides a free system called the Prior Notice System Interface, or PNSI, where anyone can file their own Prior Notice without paying a third party. It's functional and free, but it was built primarily as a compliance and enforcement tool, not as a user-friendly experience for small business owners juggling dozens of other responsibilities.
Filing it yourself through the FDA's PNSI portal
If you choose to file directly, the general process looks like this:
- Register for an account. You'll need to create an account with the FDA's Prior Notice system before you can submit any filings. This is a one-time setup step.
- Gather your shipment details. Before you start, have your commercial invoice, manufacturer details, FDA facility registration number, carrier information, and expected arrival details ready. Trying to find this information mid-filing slows the process down significantly.
- Select the correct FDA product code. Every product needs to be matched to a specific FDA classification code. This is one of the more technical parts of the process, since the coding system isn't always intuitive for products that could plausibly fit multiple categories.
- Enter line-item details for every product in the shipment. If your order has multiple distinct products, each one typically needs its own line item with its own code and description.
- Submit within the required time window. Filing too close to arrival, or after the shipment has already left, can result in the notice being rejected.
- Save and print your confirmation. Once accepted, you'll receive a confirmation that should travel with the shipment's documentation.
Where the process tends to go wrong
A few specific mistakes account for the majority of Prior Notice problems businesses run into when filing themselves:
- Incorrect or mismatched FDA product codes — choosing a code that doesn't accurately reflect the product, which can trigger a hold for clarification
- Missing or invalid facility registration numbers — if the manufacturer's FDA registration isn't current or doesn't match what's on file, the notice can be flagged
- Filing too close to the shipment's arrival — each transportation method has its own minimum lead time, and cutting it close leaves no room for correction if something's wrong
- Inconsistent information between the Prior Notice and the actual shipping documents — quantities, descriptions, or addresses that don't match between systems
None of these mistakes are exotic. They happen because the process asks non-experts to get technical regulatory details right, under time pressure, without much margin for error.
How long does filing yourself actually take?
For a simple, single-item shipment, an experienced filer might complete a Prior Notice in 10 to 15 minutes. For a more complex order with many different products, each needing its own line item and code, that can stretch to 30 minutes or more, especially for someone filing infrequently who has to re-familiarize themselves with the portal each time. Multiply that by every shipment you send to the US in a given week, and it becomes a real operational cost, not just a minor inconvenience.
The alternative: a filing service
Instead of learning and maintaining expertise in the FDA's portal yourself, you can use a service like NoticeFlow. The process from your side becomes much simpler: you upload your commercial invoice, a compliance specialist reviews the details and files the Prior Notice accurately on your behalf, and you receive a completed filing, typically within the same business day. The technical complexity of product codes, facility registration verification, and portal navigation is handled by people who do this daily, rather than something you have to learn and re-learn every time you ship.
This matters most for businesses shipping regularly. The time saved compounds: a service that takes you minutes per order to use, instead of 15 to 30 minutes of direct filing, adds up to meaningful hours back in your week as volume grows.
